4 Summary of the HP/Phoenix BIOS
Setup Program
appears in a different color, and cannot be changed.
Disabling a device in the Configuration Menu (for example, Serial port B in
the diagram above) has the advantage of freeing the resources (such as
IRQs and peripheral addresses). Disabling a device in the Security Menu
disables the access, not the device. It does not have the advantage of freeing
the resources, but has the advantage of temporarily disabling the device
without losing the configuration settings.
The
USB interface
field, in the USB Devices sub-menu, is
disabled
by
default.
The
Modem IRQ
field, in the Modem sub-menu, is used when a modem
accessory has been installed. It does not enable the IRQ on the modem. It is
used to indicate, to the System BIOS, which of the IRQ lines should wake up
the PC when the modem receives a ringing tone. It is only applicable with an
APM 1.2 compatible operating system, such as Windows 95.
